@fristi I'd just like to interject for a moment. What you're referring to as Mastodon, is in fact, ActivityPub/Mastodon, or as I've recently taken to calling it, ActivityPub plus Mastodon. Mastodon is not a social network unto itself, but rather another free component of a fully functioning ActivityPub system made useful by the ActivityPub webfingers, inboxes and vital system components comprising a full social network as defined by W3C.
The social network of the future: No ads, no corporate surveillance, ethical design, and decentralization! Own your data with Mastodon!
